Cisco 1800 Series integrated services routers are the next evolution of the
award-winning Cisco 1700 Series modular access routers. The Cisco 1841 router
(Figure 1) is designed for secure data connectivity and provides significant
additional value compared to prior generations of Cisco 1700 Series routers by
offering more than a fivefold performance increase and integrated
hardware-based encryption enabled by an optional Cisco IOS® Software security
image. The Cisco 1841 dramatically increase interface card slot performance
and density over the Cisco 1700 Series while maintaining support for more than
30 existing WAN interface cards (WICs) and multiflex trunk cards (voice/WICs
[VWICs]-for data only on the Cisco 1841 router).
The Cisco 1841 router features secure, fast, and high-quality delivery of
multiple, concurrent services for small-to-medium-sized businesses and small
enterprise branch offices. The Cisco 1841 router offers embedded
hardware-based encryption enabled by an optional Cisco IOS Software security
image; further enhancement of VPN performance with an optional VPN
acceleration module; an intrusion prevention system (IPS) and firewall
functions; interfaces for a wide range of connectivity requirements, including
support for optional integrated switch ports; plus sufficient performance and
slot density for future network expansion and advanced applications as well as
an integrated real-time clock.
Support of high-density WICs (HWICs) is optional.
Applications
Secure Network Connectivity for Data
Security has become a fundamental building block of any network, and Cisco
routers play an important role in embedding security at the customer's access
edge. The Cisco IOS Software security feature sets for the Cisco 1841 router
that enable the hardware-based encryption on the motherboard provide a robust
array of features such as Cisco IOS Firewall, IPS support, IP Security (IPSec)
VPNs (Digital Encryption Standard [DES], Triple DES [3DES], and Advanced
Encryption Standard [AES]), SSL Web VPN, Dynamic Multipoint VPN (DMVPN),
network admissions control (NAC) for antivirus defense, Secure Shell (SSH)
Protocol Version 2.0, and Simple Network Management Protocol (SNMP) in one
solution set. In addition, the Cisco 1841 router offers bundled network
security solutions with IPSEC and SSL VPN encryption-acceleration modules,
making it the industry's most robust and adaptable security solution available
for small-to-medium-sized businesses and small enterprise branch offices. As
Figure 2 demonstrates, the Cisco 1800 Series routers help enable customers to
deliver high-performance, concurrent, mission-critical data applications with
integrated, end-to-end security.
Integrated Services
The new, high-performance and secure integrated services architecture of the
Cisco 1841 router (as shown in Figure 2) enables customers to deploy
simultaneous services such as secured data communications with traditional IP
routing at wire-speed performance. By offering a hardware-based encryption on
the motherboard that can be enabled with an optional Cisco IOS Software
security image and the flexibility to integrate a wide array of services,
modules, and interface cards, the Cisco 1841 router helps enable businesses to
incorporate the functions of a standalone secure data solution.
